Scott Stammers, who pleaded guilty to conspiracy in August 2015, will be deported after serving his 181-month sentence.
Dressed in khaki pants and an olive top, Stammers declined an opportunity to address the New York court.
"No. I'm fine, thank you very much sir," he told US Federal Judge Andrew Carter yesterday.
Stammers had faced a sentence of up to 30 years, but the judge cited mitigating factors that included the fact that he has two children and was held in harsh conditions in Thailand before being extradited.

"Mr Stammers I wish you the best of luck. I hope you can get your life back on track," said Carter, expressing hope that the defendant can be the father that "your children need you to be."
He was one of five defendants arrested in Thailand in September 2013 on suspicion of preparing to ship the drugs by boat.
Two of his co-defendants belonged to a criminal gang, which claimed to have stockpiled a ton of North Korean methamphetamines in the Philippines for storage, according to US court documents.
Court documents described him as a poor student and said he got first job in private security at 18.
Within a year he was stabbed on the job, but went onto make "a good living" handling security matters across Southeast Asia, according to court filings.
Despite difficulties at school, he developed a working knowledge of Tagalog, spoken in the Philippines, Thai and Cantonese, they added.
